But Trump’s case is even weaker than Clinton’s. At least Clinton was being sued personally. He ultimately had to give evidence himself, which he did (infamously) at a deposition. But because the suit had nothing to do with presidential duties, the Supreme Court said it could proceed.
Here, Trump hasn’t been charged with or sued for anything. He’s not being required to do anything. The subpoenas have been directed at his company and his accountants. They don’t require his time or attention.
Trump’s position stupefies. In essence: Authorities can’t investigate anything touching his personal affairs — including, ahem, payments to pornographic actresses — because he’s president. Think of the logic: Not only does the president enjoy a personal constitutional immunity — his businesses do, too.
